Visual C++8 (VC8) redistributable package is a mandatory requirement for any Visual Studio 2005-built binaries (dlls/exes) which means (VC8) needs to be installed before installing any Application built by Visual Studio 2005.
Serverprotect's Management Console (MC), Information Server (IS), and 32-bit NS were built using Visual Studio 6.0 which has no concept of Manifest File. On the other hand, the 64-bit Normal Server was built using Visual Studio 2005 SP1 where the Manifest File information is embedded into the binary. This Manifest File defines what versions of Visual C++ 8.0-dependent files need to be used.
Because ServerProtect specifies an assembly dependency, SidebySide will search for the assembly among the shared assemblies in the C:\Windows\WinSxS folder. If the required assembly is not found, SidebySide will search for a private assembly where Serverprotect was installed.
But because the Visual C++ redistributable package for Visual Studio 2005 SP1 was not installed, the assembly can not be found. This error information is logged in the System Event log.
